Properties and application of terbium oxide

2019-03-06
Terbium oxide is often used to explain the electron configuration of atoms, the electronic state and bond formation of molecules, and the mechanism of REDOX reaction. Although some major group elements and transition metal elements can have very high oxidation states such as +VIII valence or even +IX valence, for lanthanide elements (Ln), they are mainly presented as +III valence due to the valence layer 4f electron inertia.The highest oxidation state of lanthanide and terbium is +IV.

 
Tb4O7 is used to manufacture metal terbium, magneto-optic glass, fluorescent powder, magneto-optic storage, chemical additive, etc.
